Atomic weight is also called relative atomic mass to reduce confusion related to the term 'weight'. Atomic weight is the averagemassofatomsof anelement, calculated using the relative abundance ofisotopesin a naturally-occurring element. It is the weighted average of the masses of naturally-occurrin...
So, when the term atomic weight was coined back in 1808, isotopes were unknown and Earth gravity was the norm. The difference between atomic weight and atomic mass became known when F.W. Aston, the inventor of the mass spectrometer (1927) used his new device to study neon. At that time...
